ClickHouse — open-source distributed column-oriented DBMS
Seems to be better than Cassandra (which cheats as it stores individual columns as standalone rows?)

leveldb - A fast and lightweight key/value database library by Google. - Google Project Hosting
Similar to SQLite but sequential reads are higher apparently (Really? Might be due to inline decompression)

Symas Lightning MDB (aka Lightning Database, LMDB)
Made by some OpenLDAP people, and allegedly one of the fastest read speeds for a NoSQL database engine.

alchemydatabase - A Hybrid Relational-Database/NOSQL-Datastore - Google Project Hosting
Yet another all RAM memory based database, though admittedly it is a weird hybrid type, built on top of Redis. Apparently now to be sucked into AerospikeDB

Apache Accumulo
An NSA designed BigTable based NoSQL key value store database with cell level access control. Originally intended for fine grained general access to intelligence information, the NSA opensourced it and handed it off to the Apache foundation due to the linkages with hadoop. Unfortunately, due to politics, the NSA might actually not get a chance to actually use Accumulo.
